Sub stopped working again. Tried to call axiom support a few times since this morning but haven't got an answer so I left a message.
I guess I'll cough up the 40-50 bucks to ship the amp to them as there is definitely a problem.
During test tones there was a pop (sounded like the sub started to work for a second), then complete silence. Turned off everything and tried again and still silence. I put the test tone onto SW and went back and turned the volume up on ep500, nothing at all until volume reached 12 oclock position then it started working suddenly.
mysteriously a ground loop hum started to appear an hour or so later, which was resolved by loosening the chasis ground screw. (I had ground loop issues before but solved them with the axiom ground isolator.) now, there is no ground loop hum with chasis ground screw screwed in or out, that problem only lasted a few minutes.
